GridView 可点击图片在下方显示为更大

Question

我正在尝试制作一个 gridview ，您可以在其中单击图像，它将以更大的图像显示在 gridview 下方。 我已经有 gridview 设置，但是我正在努力创建一旦单击图像，它将在 gridview 下方显示为更大的图像。

到目前为止我所拥有的：

公共 class MainActivity 扩展 AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    GridView gridView = (GridView) findViewById(R.id.gridview);
    gridView.setAdapter(new ImageAdapter(this));
}

}

公共 class ImageAdapter 扩展 BaseAdapter { private Context mContext;

public ImageAdapter(Context c) {
    mContext = c;
}

public int getCount() {
    return mThumbIds.length;
}

public Object getItem(int position) {
    return null;
}

public long getItemId(int position) {
    return 0;
}

public View getView(int position, View convertView, ViewGroup parent) {
    ImageView imageView;

    if (convertView == null) {
        imageView = new ImageView(mContext);
        imageView.setLayoutParams(new ViewGroup.LayoutParams(350,350));
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        imageView.setPadding(100,30,100,30);
    }
    else {
        imageView = (ImageView) convertView;
    }
    imageView.setImageResource(mThumbIds[position]);
    return imageView;
}

public Integer[] mThumbIds = {
        R.drawable.ashe, R.drawable.garen,
        R.drawable.miss_fortune, R.drawable.udyr,
        R.drawable.quinn, R.drawable.twisted_fate
};

}
